Overview
The RBS 884 Pico (1900 MHz) is a modular radio base station that is capable
of supporting all channels in the digital PCS band (1900 MHz). Each Radio
Head in the Pico system is equipped with four transceivers (TRXs) that
provide air interface communications with mobile phones.
The RBS 884 Pico (1900 MHz) provides the following features:
•
Support for 1900 MHz Telecommunications Industry
Association/Electronics Industry Association (TIA/EIA)-136
compatible mobile stations.
•
Standard digital cell configuration that supports one Mobile Location
Verification Module (MVER), one Digital Control Channel (DCCH),
and eight Digital Voice Channels (DVCs), and covers a cell radius of
approximately 30 to 50 m, depending on propagation conditions.
•
Control and operation from the Mobile Switching Center (MSC) that
is compatible with existing RBS 884 products.
•
Design that meets or exceeds TIA/EIA-136-280 Base Station
minimum performance requirements, except for the radio frequency
(RF) sensitivity (-105 dBm).
•
Compliant with the following regulatory agencies:
–
Nationally Recognized Testing Laboratory (NRTL)
–

RBS 884 Pico (1900 MHz) Components
The RBS 884 Pico (1900 MHz) consists of a CRI that interfaces with remote
Radio Heads. The product is used for spot coverage in larger 1900 MHz
systems or for indoor wireless systems.
The RBS 884 Pico (1900 MHz) control hardware is installed in a standard
19-in equipment rack or an optional floor mount cabinet. The radio hardware
is installed on a wall or other vertical surface separate from the CRI hardware.
With leased T1/E1 connections between the CRI and Radio Heads, the CRI
can be centrally located and the Radio Heads can be installed in separate
buildings. With non-leased connections between the CRI and Radio Head,
the maximum cable loss between the Radio Head and the CRI is 30 dB. This
cable loss restriction allows the first Radio Head to be located 800 m to
1000 m from the CRI (as measured by cable length).
To comply with FCC RF exposure requirements, the external antennas used
with this device must be mounted to provide a minimum separation distance
of 20cm (8 inches) from all persons, with the antenna gain not exceeding 14
dBi. Amplifiers and boosters are not permitted.

RBS 884 Pico Call Path and Signaling
2.1.1
Control Signaling
Control signaling for the RBS 884 Pico (1900 MHz) system is as follows:
2.1.2
•
The MSC central processor sends the control signal to the Signaling
Terminal Central (STC) unit.
•
The STC unit converts the signal format and sends the signal to the
Exchange Terminal Circuit (ETC).
•
The ETC inserts the control signal into a time slot on the PCM
T1/E1 link to the base station CRI.
•
The ETB extracts the control signal and sends it to the STR.
•
The STR converts the information back to processor format and
outputs it on the Extension Module Regional Processor Bus
(EMRPB).
•
The EMRPB connects the processing units (EMRP and EMRPSs).
–
The EMRP controls the CRI hardware units, including the
RITSW, ETB, and ELI.
–
The EMRPS (through the ELI) controls the TRXs in the Radio
Head. The T1/E1 network connection with Link Access
Protocol D (LAPD) provides error detection and retransmission.
Speech Signaling
Speech signaling for the RBS 884 Pico (1900 MHz) system is as follows:
2-6
•
The Public Switched Telephone Network (PSTN) sends a speech or
data signal to the Group Switch (GS) at the MSC.
•
A digital call is processed by the MSC as follows:
–
Routed to the Transcoder Rate Adaptation Board (TRAB)
–
Converted into compressed format used in the air interface with
Algebraic Code Excited Linear Prediction (ACELP)
1/1551-AE/LZB 119 3834 Uae Rev PA 2001-03-05
System Description
•
2.2
–
Combined with two other voice paths that share the same
frequency
–
Routed to the correct ETC
The signal is sent over a T1/E1 line to the base station CRI where it
is routed to the following units:
–
ETB
–
RITSW
–
ELI
•
The ELI unit communicates with TRXs in the Radio Head through a
T1/E1 line.
•
In the Radio Head, the RHI receives the signal and routes it to the
correct TRX, where it is converted to RF. The RF is then filtered and
coupled to the antenna(s) for transmission.
Synchronization
Synchronization is necessary to ensure a stable carrier frequency reference
and error-free transmission between the RBS and the MSC.
Jitter and wander introduced by the T1/E1 line between the CRI and the
Radio Head is filtered out by the Radio Head Phase Locked Loop (PLL). The
frequency accuracy of the Radio Head is better than 0.1 ppm at the presence
of maximum wander (138 UI), provided that the reference frequency for the
PLL is traceable to a long-term Stratum 2 clock reference from the network.
With non-leased or proprietary connections between the CRI and the Radio
Head, the ELI unit is connected to the incoming MSC PCM Stratum 2
reference. The T1/E1 connection on the ETB unit is cabled to the first ELI
unit. The first ELI unit uses the PCM reference to provide the transmit clock
for the PCM interface to the Radio Heads. The reference from the first ELI
unit is passed to the other ELI units through the ETB-ELI Sync Cable.
Architecture
The RBS 884 Pico (1900 MHz) controls and handles communication
between the MSC and the mobile stations. The configuration of the Pico
equipment depends on the following:

General Overview of RBS 884 Pico (1900 MHz) Configuration
The GS at the MSC is responsible for switching calls between subscribers.
The calls can be between two mobile subscribers or between a mobile
subscriber and a subscriber in the public telephone network. The RBS
1/1551-AE/LZB 119 3834 Uae Rev PA 2001-03-05
2-9
System Description
contains several regional processors that are controlled by and work with the
central processor. The regional processors control the time switch and the
TRXs in the base station. The time switch in the base station makes sure that
the speech signals from the MSC are connected to the correct TRX. The
TRXs generate radio signals that are emitted by the base station antenna
to the mobile stations. The semipermanent connections are set up in the
MSC. Each TRX handles three digital speech channels, but uses only one
channel on the T1/E1 PCM link.
The RBS 884 Pico (1900 MHz) is an application of the Mobile Base Station
Subsystem (MBS) and follows the same general functional structure. The
basic functional and implementation structure is shown in Figure 2-3
on page 2-11.

The following paragraphs describe the hardware units used in the RBS 884
Pico (1900 MHz) CRI magazine.
3.2.1.1
DC/DC Power Converter Units
The CRI has two DC/DC converter units that supply power to the CRI
subrack. The converter units receive power from a single +24 Vdc power
feed and convert it to ±5 Vdc for use by the CRI boards.
1/1551-AE/LZB 119 3834 Uae Rev PA 2001-03-05
2-17
System Description
Each DC/DC converter unit is capable of powering the entire CRI subrack in
case of failure of one of the units. When both units are operational, they
share the load. The EMRPSs have onboard DC/DC converters.
3.2.1.2
Exchange Terminal Board (ETB)
The ETB unit provides a T1/E1 network interface to the MSC. It is available
in a 24 time slot T1 version (ETB24) or a 32 time slot E1 version (ETB32).
The physical T1/E1 interface is a quarter-plug connector on the front
panel of the ETB. The unit provides frame synchronization and time slot
extraction/generation of the T1/E1 signal.
The ETB routes the speech DS0 signals to the RITSW over the CRI
backplane. The ETB extracts base station control information from a single
T1/E1 time slot. This signal is routed to the STR. The ETB also extracts the
8 kHz frame clock from the network interface link. The frame clock provides
the Carrier Frequency Reference (CFR) to the RITSW.
3.2.1.3
Signaling Terminal Regional (STR)
The STR is a protocol converter that communicates with the STC in the
MSC. Communication with the MSC is through a single DS0 time slot
on the MSC-CRI span. This time slot is routed from the span to the STR
by way of the ETB. In addition, the STR generates the EMRPB interface
within the CRI.
3.2.1.4
Extension Module Regional Processor (EMRP)
The EMRP is controlled by the MSC. In turn, the EMRP controls the ETB,
ELI, and RITSW through the backplane Device Control Bus (DEVCB). The
EMRP communicates to the MSC through the EMRPB provided by the STR.
The EMRP executes regional software downloads from the MSC.
3.2.1.5
EMRP with Speech Bus Access (EMRPS)
The EMRPS is an EMRP with extended processor power and a speech bus
interface. The EMRPS implements the logical parts of the radio channel
functions for the RBS 884 Pico (1900 MHz). The EMRPS executes software
downloads from the MSC.
The EMRPS unit communicates with the MSC through the EMRPB
interface. Communication with the Radio Heads is through the RITSW
and ELI units by way of the DEVSB interface in the CRI backplane. The
EMRPS unit is equipped with an onboard DC/DC converter that derives the
required internal voltages from the CRI backplane.
2-18
1/1551-AE/LZB 119 3834 Uae Rev PA 2001-03-05
System Description
3.2.1.6
Enhanced Link Interface (ELI)
The ELI is used to provide a T1/E1 connection between the CRI and the
Radio Head. The device supports a single, 100-ohm twisted-pair 1.544
Mbit/s long-haul or short-haul T1 interface, or a single, 120-ohm twisted
pair or 75-ohm coaxial 2.048 Mbit/s long-haul or short-haul E1 interface.
The ELI unit contains switches to select the link type (T1/E1 leased or
non-leased), short-haul T1 line build-up, long-haul attenuation and the
75-ohm coaxial E1 cable grounding.
The ELI maps the DEVSB time slots from the RITSW to the T1/E1 time
slots using a predefined multiplexing and mapping scheme. The ELI also
handles the LAPD-based retransmission protocol at the CRI end of the
connection. On the Radio Head end, the RHI unit handles all time slot
mapping and retransmission functionality
The T1 interface utilizes Extended Superframe (ESF) framing format and
Bipolar with 8 Zero Substitution (B8ZS) line code. The E1 interface utilizes
Frame Alignment Signal-Cyclic Redundancy Check (FAS-CRC) framing
format and High Density Bipolar Level 3 (HDB3) line code.
A Light Emitting Diode (LED) lamp on the ELI indicates the status of the
T1/E1 line. The ELI transmits the T1/E1 alarms back to the Radio Head
corresponding to the quality of the signal received on the T1/E1 line from the
Radio Head. The ELI can be monitored and controlled by the EMRP through
the backplane DEVCB with Digital Path (DIP) supervision.
See Figure 2-8 on page 2-19 for an illustration of ELI unit and Radio
Head connections.

System Description
3.2.1.7
Radio Interface Time Switch (RITSW)
The RITSW is a local space/time switch in the CRI that routes DS0 time
slots between ETB, EMRPS and ELI. The RITSW also provides the clock
synchronization and stabilization in the CRI.
The RITSW is controlled by the EMRP through the backplane DEVCB.
The DEVCB interface to RITSW is used to set the semi-permanent DS0
time-slot connections.
3.2.1.8
Fan Unit
The Fan Unit is a physically separate part of the CRI subrack and is mounted
directly above the subrack. The Fan Unit contains two fans that are powered
by the DC/DC converters in the subrack. The fans are rated such that a single
fan can provide sufficient cooling of the CRI.
3.2.1.9
Cabinet Identification (CID) Unit
The CID Unit is located on the top-left side of the CRI floor mount version
and on the bottom-left side of the CRI rack mount version. The CID Unit
allows a unique identification number to be set for the CRI cabinet during
installation. This number is read at the MSC to identify the cabinet for
alarm reporting and fault resolution.
3.2.1.10 Internal Alarm Distribution
The CRI distributes and reports the following equipment related alarms:
•
Fan alarm
•
DC/DC converter alarm
The alarms are distributed in the CRI as shown in Figure 2-9 on page 2-21.

External AC/DC Power Supply Unit (PSU)
The external AC/DC PSU is housed in a 19 in rack-mountable assembly. The
PSU draws power from the building 110 (50-60 Hz) or 220 Vac (50-60 Hz)
power receptacle, and supplies +24 Vdc (nominal) through the DC filter
units to the DC/DC converters in the CRI cabinet.
Note:
The external AD/DC power unit does not have an ON/OFF
switch. The only means for switching the PSU on/off is by
plugging and unplugging it from the building power receptacle.
The CRI should be installed within easy access of the building
power receptacle.

System Description
3.2.3
Radio Head
The Radio Head implements the MOP functionality and part of the ANP
and SUP functionalities. The Radio Head is located in a custom enclosure.
RF shielding minimizes coupling of signals into and from the RF circuitry
and allows compliance to EMI and EMC specifications. The Radio Head
contains two DTRX units for a total of four TRXs in each Radio Head.
The Radio Head is mounted on a pre-mounted support bracket that is
installed on a wall, column, pole, or other vertical surface. Modular RJ-45
connectors, mounted on the top of the Radio Head, provide connections for
the primary and secondary PCM link cables.
The Radio Head has its own internal power supply that must be connected to
the standard mains power through the AC power plug connector.
RBS 884 Pico (1900 MHz) Radio Head uses two Transmit/Receive (TX/RX)
antennas. The Radio Head antennas can be either monopole, patch, or
external antennas.
See Figure 2-10 on page 2-22 for an illustration of the Radio Head with
monopole antennas. See Figure 2-11 on page 2-23 for a Radio Head block

System Description
Equipment Configurations
The RBS 884 Pico (1900 MHz) Radio Heads can be connected to CRI
equipment through non-leased (proprietary) or leased T1/E1 links. Within the
RBS 884 Pico (1900 MHz) system, Radio Heads can be separately located in
individual cells or colocated within a single cell. Both arrangements allow
for cascade connections of up to three Radio Heads with a single proprietary
or leased link and up to ten Radio Heads with four links. Refer to Figure 2-2
on page 2-9. The maximum cable loss between Radio Heads is 30 dB.
The maximum cell radius for all cell types is approximately 30 to 50 m (98
to 164 ft) or an approximate area of 2,826 to 7,854 sq m (30,170 to 84,500
sq ft), depending on the propagation conditions.
Refer to Figure 2-15 on page 2-29, Figure 2-16 on page 2-30, and Figure
2-17 on page 2-31 for examples of possible configurations.
Note:

Each system implementation is unique and may not be
completely represented in this manual. Detailed configuration
information is provided in Part 5 Configuration and Test.

RBS 884 Pico (1900 MHz) CRI Installation
Introduction
This document contains step-by-step procedures for installing and cabling
the Control and Radio Interface (CRI) for the RBS 884 Pico (1900 MHz)
System. Additional information is also provided for adding RBS 884 Pico
functionality to an existing RBS 884 Macro (1900 MHz) CRI unit.
Note:
The Radio Head installation procedures for the RBS 884 Pico
(1900 MHz) are described in Part 4, RBS 884 Pico (1900 MHz)
Radio Head Installation.
Safety Precautions
Before starting any installation, test, or maintenance procedures, review the
safety regulations provided in this section and any other applicable parts
of this manual. Additionally, the installer is responsible for determining
that the installation conforms to all applicable electrical, mechanical,
communications, and construction codes.
Carefully review each procedure before starting, including the
admonishments (dangers, warnings, and cautions) that are applicable to
the procedure.
2.1
Voltage Hazards
DANGER!
Hazardous voltages over 100V are used in the operation of this equipment.
Use extreme caution when working on energized equipment. Contact with
AC power of any voltage can cause injury and sometimes death.
Always observe the following:
•
Shut off the power supply, if possible, before working on the
equipment.
•
Remove all jewelry before working on the equipment.
1/1531-AE/LZB 119 3834 Uae Rev PA6 2001-04-04
3-3
RBS 884 Pico (1900 MHz) CRI Installation
2.2
•
Do not touch high voltage connections when installing or operating
the equipment.
•
If possible, keep one hand away from the equipment to reduce the
possibility of current flowing through vital body organs.
Radio Frequency Radiation
Warning!
Radio frequency from an antenna may be a danger to health, causing severe
burns to skin and clothing.
Notify the MSC to switch off the transmitters if you work with or near
antennas.
2.3
Beryllium Oxide
Some equipment contains beryllium oxide in ceramic form.
Warning!
Beryllium oxide is poisonous and constitutes a health hazard if present in
finely dispersed form, such as dust or smoke, which can be inhaled. Read
local hazardous chemical regulations before working with beryllium oxide.
Units with components containing beryllium oxide are marked with a
warning label. For detailed information about properties, health and
environmental hazards, refer to the regulations issued by the local authorities.
The following rules must be obeyed by all persons handling beryllium oxide:
3-4
•
Ceramics containing beryllium oxide must not be scraped, filed,
ground, treated with acid, or machined in any other way.
•
Compressed air must not be used to clean units containing beryllium
oxide.
•
Always wear protective gloves when handling beryllium oxide.
•
Use wet rags to collect dust and particles from damaged beryllium
oxide components. After use, place the rags in plastic bags and
seal the bags completely.
1/1531-AE/LZB 119 3834 Uae Rev PA6 2001-04-04
RBS 884 Pico (1900 MHz) CRI Installation
Scrapped beryllium oxide must be treated as environmentally hazardous
waste. Local authorities enforce regulations regarding the treatment and
disposal of environmentally hazardous waste. Investigate the applicable
local regulations and comply with them.
2.4
Heavy Loads
Warning!
A heavy load (anything over 10 kg (22 lb) lifted incorrectly can cause injury
to persons and damage to the equipment. A factory-shipped RBS 884 Pico
CRI cabinet weighs approximately 30 kg (66 lb).
Electrostatic Discharge
The human body acquires static charge in all situations involving movement.
The same effect is achieved when handling ordinary plastic materials.
If the body comes into contact with a grounded Integrated Circuit (IC)
component, this static charge may cause an Electrostatic Discharge (ESD)
resulting in a spark and damage to the component.
Note:
3.1
To avoid component damage because of ESD, always follow
the instructions for handling sensitive electronic components
and circuit boards. Personnel must always use ESD protection
equipment when working with such components and circuit
boards.
Storage and Transport
Store and transport components and hardware units in their original
packaging.
Alternatively, use a conductive material or special IC carrier that either
short-circuits all contacts and pins or insulates them from external contact.

3.2
ESD Wrist Strap
When working with circuit boards, wear an ESD wrist strap to avoid ESD
damage to the boards. The strap can be connected to the collection bar
located in every cabinet shelf, as shown in Figure 3-1 on page 3-6.
Follow local procedures on testing the wrist strap.

Coaxial Connectors
Push the coaxial connectors firmly in place. Tighten the connectors, first by
hand, then with a torque wrench set to the torque specified in this manual.
Use of the proper torque settings prevents damage to the connectors and
ensures optimal connection.
Caution !
Coaxial connectors are especially sensitive after tightening. Do not try to
change direction of the outgoing cable after tightening. Do not use the
outgoing cable as a tool to tighten the connector.
Note:
Figure 3-5.
The N-connectors (with a cross-hatched ring) shown inFigure
3-5 on page 3-9 can be sufficiently tightened by hand and, thus,
do not require a torque wrench.

Cabling the CRI Hardware
10.1.1 Installing the ETB-ELI Sync Cable
Preparations
1.
Locate the ETB-ELI sync cable.
Note:
The ETB-ELI sync cable is required for non-leased
or proprietary connections. The sync cable is not
required for T1/E1 leased connections, although its
presence does not interfere with leased connections.
ETB-ELI Sync Cable
2.
Connect the quarter-plug connectors on the ETB-ELI sync cable (RPM
113 7673) to ELI unit, positions 17–21, B4. Refer to Figure 3-50 on
page 3-64 for an example of the sync cable connections.
Note:
1/1531-AE/LZB 119 3834 Uae Rev PA6 2001-04-04
The order in which the quarter-plugs are connected
does not affect the performance of the base station.
However, it is important to connect the first ELI
quarter-plug connector to one of the ELI units.

RBS 884 Pico (1900 MHz) CRI Installation
Preparations
1.
Ensure that the Radio Heads are properly installed and tested prior to
starting this installation procedure.
Note:
2.
The first or primary Radio Head in each link or link
group must be installed and connected to the PSTN.
Additional Radio Heads are installed after the initial
communication is established between the CRI and
the primary Radio Heads.
Determine the number of Radio Head link groups (usually determined
by the number of T1/E1 links). Refer to Figure 3-51 on page 3-66 and
Figure 3-52 on page 3-67 for configuration examples.
Note:
1/1531-AE/LZB 119 3834 Uae Rev PA6 2001-04-04
If the number of Radio Heads or Radio Head link
groups to be connected to the CRI is not known,
consult the next level of maintenance support or
the site engineer.

DANGER!
Do not install T1/E1 PCM cable close to fluorescent light fixtures,
transformers, or electric motors. For cabling practices, see
“Commercial Building Standard for Telecommunications Pathways
and Spaces, EIA/TIA-569.”
If the CRI is remote and the line to the CRI is leased, install a Channel
Service Unit (CSU) and route a T1/E1 PCM cable from the CSU to the
first Radio Head (Radio Head 1). If the CRI is local and the line to
the CRI is proprietary or non-leased, route the cable directly from the
local CRI to Radio Head 1. Refer to Table 4-8 on page 4-35 for the
technical specifications for the PCM connections. See Figure 3-53
on page 3-69 and Figure 3-56 on page 3-74.
